I do agree it's hypocritical of Clarke to sledge like he does etc. However, I blame the batsmen more nowadays. They don't need to take on the short bowling, they could just get out the way but it seems to be expected by the public and coaches that they attack the short ball. If you are going to attack it then I sort of think the bowler should be able to 'attack' you. After all, it's biff cricket already let alone if we told bowlers they had to bowl x length or more.. might as well just sack off bowling, use a machien and have a baseball style slog fest.
If batsmen ducked/swayed then the umpires could call a halt to the bouncer barrage as it's not softening them up etc, it's just being intimidating. However, if the batsmen is taking it on, then I'm all for the bowler having a go at them, the modern game with flat tracks, short boundaries is too batsmen friendly already.
